PLOS Biology Topics

Ever wonder what topics are discussed in PLOS Biology articles?
Here I will apply an implementation of Latent Dirichlet Allocation (LDA)
on a set of 1,754 PLOS Biology articles to work out what a possible collection of underlying topics could be.

I noticed that the word figure occurs rather frequently in these articles, so let us exclude this and any other words
that appear in more than half of the articles in this data set (thanks to Radim
for pointing this out to me).
